研究人员开发了一种新的地面生成评估指标，解决了现有以精度为中心的方法的局限性。当前指标常常奖励模型不发表声明，导致输出质量低下且信息不足。通过引入“覆盖率”或召回率成分，该新指标在F1赛车遥测和天气预报上进行了演示，揭示即使是表现最好的模型也未能覆盖相当一部分相关事实。 AI
影响 引入了更鲁棒的AI生成评估指标，推动更全面、更少回避的输出。

Reference-free faithfulness metrics verify each atomic claim a model makes against ground truth, and are increasingly used to evaluate grounded generation. We show they share a blind spot: they measure only precision -- are the stated claims supported? -- and therefore reward abs…
Reference-free faithfulness metrics suffer from a blind spot measuring only precision, leading to rewards for abstention; completeness in deterministic domains enables measurement of both precision and recall, revealing that high-precision models often have poor fact coverage.
